Unlike the E90 LCI, the F30 does not have flashing Emergency Stop brake lights. Instead, the outside (normal) brakelights are activated and then the inside brake lights also illuminate brightly. The hazard lights are deployed when the car comes to a stop.

No problem! I think the F10 5 Series still flashes, and the E90 LCI does for sure, but not the F30 interestingly.

the dynamic breaking lights just senses how hard and how fast youre steping on the breaks.
the flashing hazard lights will come on if you didnt turn off any dtc and lose tire grip for over 2 seconds and keeps flashing till traction is restored

it happened to mine when i was messing around in the snow with traction control on but didnt happen when traction control was off

I was close to crashing some time ago, it was raining and my runflats were utter crap.. After breaking hard the ABS came in and i slid across the road for about 8 meters. Then came to a stop, i remember seeing the hazards come on as soon as i lost traction on the 4 wheels, i had to press the hazard button to turn them off when i recovered from the shock.

In any case, the car will warn the ones behind you when you get into trouble.

It's not really the hazards in question. It's more that it seems in the US the brake lights don't flash (instead, an additional one is lit as in the vid above) and in the UK, the manual suggests the brake lights will flash (though it's tricky to test?!)

Just find a stranger on the side of the road and ask them to observe you fly by and slam on your breaks...
